Getting Started - DSP
The SXD power amplifier features sophisticated high-performance DSP with control for the input and output routing, filter
network, EQ, limiter, and time alignment delay. Follow these steps to navigate through the SXD internal DSP settings:
1. Turn the SXD power ON. The startup screen will be displayed (figure 1).
2. Press the UP & DOWN buttons to step through the DSP parameters (figure 2).
3. Rotate the EDIT knob to adjust settings. A box will flash in the upper right corner when a set-
ting has been changed (figure 3).
4. Press the EDIT button to confirm and set the changes. Press any other button to cancel the
adjustment.
5. Press the BACK button to exit out of a parameter and return to the top level of the menu.
DSP Settings
Preset - Choose either Manual Mode, which provides access to the full set of adjustable parameters, or from the four speak-
er presets: 2 full range, Mono 2-way, Sub/Sat, or 2 subs.
I/O - The I/O screen adjusts the settings for how the inputs will be routed through the DSP to the output connectors.
Stereo: Ch A Input -> Ch A Output & Ch B Input -> Ch B Output
Mono A+B dual: Ch A and Ch B inputs are mixed together, each level control adjusts the corresponding output level
Mono A+B link: Ch A and Ch B inputs are mixed together, Ch A level control adjusts both Ch A and Ch B output levels
Parallel A dual: Ch A input is sent to both Ch A and Ch B outputs, each level control adjust the corresponding output level
Parallel A link: Ch A input is sent to both Ch A and Ch B outputs, CH A level control adjusts the output level for both chan-
nels.
Filter (Manual mode) - The filter section allows you to build you own crossover or add speaker protection by stetting the
filters to remove the upper and lower limits of the audio bandwidth.
Filter Ch A - Press the Edit button to enter the filter parameters for channel A.
Filter Ch B - Press the Edit button to enter the filter parameters for channel B. If the Ch A filter is On, then the Ch B filter
can be set to the same settings by choosing A=B
LPF Freq - Rotate the EDIT knob to adjust the low pass filter frequency.
LPF Slope - Rotate the EDIT knob to adjust the filter type and slope roll off in dB per octave.
HPF Freq - Rotate the EDIT knob to adjust the high pass filter frequency.
HPF Slope - Rotate the EDIT knob to adjust the filter type and slope roll off in dB per octave.
X-Over (speaker preset) - When using a speaker preset, the filters are already configured for a crossover. This allows you to
easily set the crossover frequency for your speaker configuration.
Gain Offset (Manual mode) - This adjustment allows you to set an overall balance between the outputs of the amplifier. This
allows you to match the difference of output level of the speakers in a system without needing to constantly adjust the front
panel level controls.
